Once every few hundred thousand years the magnetic poles flip so that a compass would point south instead of north. While changes in magnetic field strength are part of this normal flipping cycle, data from Swarm have shown the field is starting to weaken faster than in the past. Researchers think power grids and communication systems would be most at risk. Is there work that you are engaged in that could help mitigate the effects of our world turning ‘upside down’???
Changes measured by the Swarm satellite show that our magnetic field is weakening 10 times faster than originally predicted, especially over the Western Hemisphere. The Swarm satellites not only pick up signals coming from the Earth’s magnetic field, but also from its core, mantle, crust and oceans.

I fondly remember the Disney ride attraction “Mission to Mars” that my family and I would experience during each trip to Walt Disney World in Kissimmee, Florida. During the ride, the seats in the attraction would simulate the vibrations and G-forces from “Hyper-space” during take-offs and landings by filling up with compressed air. That ride has since been retooled a few times and morphed into Stitch’s Great Escape!
That memory came to the forefront of my brain when I read about the mission that six people will embark upon when they enter a 36 foot diameter geodesic dome on the slopes of the second biggest volcano in the solar system in Hawaii. And, to be sure, they are not there on vacation.
This team is beginning an eight-month mission funded by the US space agency NASA to test if humans will be able to withstand the long periods of confinement in a tight space that will be required to send a manned space mission to Mars some time around 2030. For Martha Lenio, the 34-year old renewable energy entrepreneur who is commanding the mission, it is something else besides: a chance to explore the furthest frontiers of sustainability.
These engineers, who were hand-picked by NASA for their contribution to sustaining life within the pod, will have to be more self-sufficient than lunar astronauts who are in constant contact with Earth, Lenio said.
“Maybe all the things we learn about sustainability along the way will turn out to be the most useful thing about going to Mars,” said Lenio.
What a great opportunity for these six engineers – you never know what great adventure may come your way with the skills you possess.
The somewhat silly and obvious reply, “To get to the other side”. Now, there’s an alternative response to those who are making inquiries about Saudi chickens… “To find a warm spot that’s not powered by diesel!” Rising costs of diesel fuel are cutting heavily into the ability for Saudi poultry farms to stay competitive. Changes must be made to address this problem – and they are in the works.
“Hybrid solar-diesel systems are an effective solution to provide power to poultry houses, many of which are not connected to the national electric grid. Solar-based solutions are well adapted to the Kingdom’s sunny conditions, and they can help reduce the poultry industry’s heavy reliance on diesel fuel,” said Mark Webster, agribusiness and food practice lead at PricewaterhouseCoopers (PwC).

Keeping people’s homes warm by use of hybrid fuel systems is gaining in popularity worldwide. Why shouldn’t our feathered (or furry, or scaly, or finned) friends enjoy the same benefits that humankind has recently embraced? After all, they’ve relied on the power of the sun to sustain them for millenia! What innovative plans do you have in mind for reducing our reliance on cost-inflated and ever-shrinking supplies of fuels?
